Abstract


According to ULCS production practice in domestic steel, sampling the carbon content of inspection RH, tundish and slab, analysis related raw materials impact carbon increasing in liquid steel, and put forward some corresponding control measures. The impact of carbon increasing for liquid steel by the raw and supplemental materials from big to small in turn as follows: mold flux, coverture, refractory, reduce the original carbon content of the raw and supplemental materials, and some oxidant such as MnO2 are added in the mold flux can effectively reduce carburization.
